Under some circumstances it may be desir able in some cases to providean external globe 26. A water tight connection is also desirable betweenthe globe 26 and the c aeing 5. 'lhis may be provided by a yieldinggasket 27. To hold the globe in place l may provide a ring 28 which maybe clamped to the casing 5 by screws. 29. A yielding gasket 30 may beinterposed between the ring 28 and a shoulder of the globe near itsbase. Suitable Ouard wires 31 may be provided and secured to the ring 28in any suitable manner so as to mechanically protect the glass and alsoso as to prevent tampering with the lamp and its connections. A switch3a of the conventional type is indicatedas connected in the low tensionleads to the transformer and as operable from the exterior of the casing5.

lt will be understood that the transformer and socket combination may bemade and sold as a unit for installation in various ways 1t will also beunderstood that the construction of the lamp per se is not material tomy present invention. 1n fact in place of the helical tube shown in Fig.1 l may employ a tubehaving a spiral conformation as shown in llig. 2 at32 which latter affords a broad surface especially when viewed from thefront light concentration. Such gas tubes may also have the form ofindividual letters or words.

rfhese lamp sockets are preferably installed in protective housings asabove described and anyV number may be used collectively. 'llhese lampsmay be provided individually with switches preferably on the low tensionside, as indicated at 34: or other suitable operating means may beemployed so that the lamps may be individually controlled immediatelyadjacent the light source or the control may be from a distant point orpoints of the low tension circuits thereof. y

The cup member 7 serves as a container for the transformer and by.virtue of its shape it allows the employment of insulating media to forma suitable circuma'mbient milieu for the transformer. The employment ofsuch insulating 'media to completely surround a transformer, forpurposes of protection against moisture, greater insulation, bettercooling or similar purposes, is well known in the electrical art anddoes not constitute an essential part of my invention.

It will be seen from the foregoing that l have endeavored to arrange asystem and construction by which these gas lamps may be* made, sold andinstalled v ery much the same y as incandescent filament lamps arehandled. A

The commercial and utilitaman advantages of such a construction andinstallation will be apparent.

I claim: l

1. A gas lamp socket having two insulatresaeae ing parts directlyfastened to one another and substantially enclosing a chamber betweenthem, a step-up transformer supported -by one part in said chamber andhaving output leads Secured to the other part, the latter part havingcontact terminals for tube prongs.

2. A gas lamp socket having an insulating part with a recess in itsupper face and an extension chamber, contacts mounted in said' chamber,an insulating shield secured insaid recess and having passages for tubeprongs and a step-up transformer having its output leads connected tosaid contacts.

8. A gas tube socket having insulating parts a step-up transformermounted in one part, the other insulating part having chamberscontaining prong contacts connected to the high tension leads of saidtransformer and an insulating shield having passages for prongs leadingto the contacts.

Il. A. gas tube socket comprising a metallic housing, an insulating cupsupported in said housing, a step-up transformer supported in saidcup.,- a switch in the low tension side of the transformer, and aninsulating part sup ported on the cup and having contacts for a tubeconnected to the output of the transformer.,

5. i gas tube socket having insulating parts a step-up transformermounted in one part, a snap switch associated with the low tension sideof the transformer, the other insulating part having chambers containingprong contacts connected to the high tension leads of said transformerand an insulating shield having passages for prongs leading to thecontacts.

6. Gas lamp apparatus comprising a casing consisting of a cup member andan insulating socket forming a closure for the casing, a transformerenclosed in said casing, and prong contacts in the insulating socketconnected directly to the high tension output of the transformer saidsocket having individual passages for prongs leading to said contacts.

A gas lamp structure comprising a transformer casing, an insulatingsocket mounted thereon and forming a closure therefor, said sockethaving spaced recesses in its i I'GCESSGS.
